- BRUSH-HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 673,541, dated May 7, 1901.

Application filed September 5, 1900. Serial No. 29,044. (No model.)

' which form a part of this specification.

This invention relates to the class of brushholders that are capable of an adjustment of the handle with regard to the brush.

It has for its object to produce an improved brush-holder to secure thehandle to the brush,

' so that it can easily be set at any desired angle to the brush without the use of a wrench or any separate device, and that shall be simple in its construction, holding the brush positively when set.

It is fully explained and illustrated in this specification and the accompanying drawmgs.

Figure 1 shows a side view of the brushholder with a part of the handle and socket in section. Fig. 2 is a view of the same as Fig. l with a modification of the mode of closing the clamping members. Fig. 3 is a view of the movable parts.of the holder with one side removed. Fig. 4 shows one of the halves of the clamp and the handle in a different position. Fig. 5 shows the inside of one of the outer parts of the holder separate, the two parts being alike. Fig. 6 is an edge view of one of the outer parts of the holder. Fig.

. 7 is a view of the inner member of the holder that is to be attached to the brush. Fig. 8 shows an end view of Fig. 7.

The construction and operation of the brush-holder are as follows:

A is the member of the combination that is intended to be attached to the brush. It is shown separately in Fig. 7. It consists of a metal body having a row of V- shaped gearteeth a around the middle and another like set of teeth a around its upper end. (See Fig. 8, which is an end view.) The lower part D, below the middle row of teeth a, is extended down to form a shank D, suitable to go into a hole in the back of a brush, with a washer and a nut r screwed on the end to hold the brush on, and ridges 0 0 are made on its sides to prevent it from being turned in the brush and unscrewing the nut 'r.

In Figs. 4, 5, and 6 is shown one of the clamping members 0 O, which are alike in every way and may be cast from the same pattern. They are shown as being hemispherical in shape in the lower part, with semicircular cavities c a, made in them, that are surrounded by rows of radiating V-shaped teeth 61, agreeing with those on the center piece A. Their upper parts h h are extended up to form when put together, as in Fig. 1, a round tapering shank to be attached to the brush-handle g, and a screw-thread is made on the outside of the two parts to fit into a like thread made on the inside of the ferrule 11 on the handle g, and when the handle is turned it will screw onto the shank h and because of its taper will close the two parts 0 0 onto the middle part A and hold it fast from moving, as the teeth (1 cl will engage with the teeth a a.

Fig. 3 shows how the part A occupies the cavity 0 in one of the parts 0, with the teeth a a engaged with the teeth 01 d of the circle, and when the other part 0 (see Fig. 5) is put on the whole will appear as in Fig. 1, with the member A inclosed between the clamping parts 0 C. It will readily be seen that if the two parts 0 O are allowed to separate a little ways by turning the ferrule n by the handle g, so as to free the teeth a, and d, the clamping members 0 may be turned around horizontally in any direction, and they may also be turned to any angle vertically, as shown in Fig. 3. The two parts 0 C may also be closed by means of the hollow socket n if it is made smooth inside and there are no screw-threads on the shank h, so the socket will slide down on the parts 0 O and compress them closely to the center piece A and by the engagement of the teeth a a with the teeth d d make a positive holder that will break before it will change its position.

Having thus described my improvements, I claim as my invention and desire to secure by'Letters Patent 1. A brush-holder consisting of the combination of acenter member having one or more rows of teeth around it, two clamping members each having a circular row of teeth on its inner face, engaging with the teeth on said central member, with means for closing said clamping members on said central member, substantially as described.

2. In a brush-holder the combination of a central member having a row of teeth around one end, a shoulder around it just inside said row of teeth, a second row of teeth near its middle, a shank on the other end of the member to secure it to the brush by two clamping members having recesses to receive said shoulder,'and rows of teeth to engage said teeth on the central member, with means for closing the clamping members to the central member, substantially as described,
